FRUIT-JAR.

SPECIFICATION forming part of Letters Patent No. 288,983, dated November27, 1883.

Application filed May 17. 1883 (No modelll To all whom it may concern Beit known that I, Josnrn: L. DE STEIGER, a citizen of the United States,residing at La Salle, in the county of La Salle and State of Illinois,have invented certain new and useful Improvements in Fruit-Jars, and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The object of my invention is to provide a fastening which is adapted tomolded glass fruit-jars.

The fastening of which this invention con sists embodies theadvantagesand accomplishes the purposes which are fully set forth in theapplication for Letters Patent of the United States for improvement infruit-jars, filed by me January 17, 1883.

In the drawings which illustrate my. present invention and make part ofthis specification, Figure l is a perspective View of the cover of afruit-jar, and Fig. 2 an elevation of 1 the upper part of a fruitjarconstructed in accordance with my invention.

The cover A is stamped or otherwise formed out of sheet metal, so thatit shall have inwardly-projecting ridges a-a, preferably three innumber. Each ridge a is concavo-convex in shape, the highest pointbeingnear the top of the cover, and curves downward equally and gradually onboth sides to near the rim of the cover. The ends of adjacent ridges approach near to each other, but are sufficiently far apart to permitoutwardlyprojecting lugs. b b. molded on the neck of the jar B, toeasily pass between them.

To permit of the molding of the lugs on the neck of the jar, they arebeveled on the top (and sides. The lugs '11 1) correspond in number tothe ridges c a on the cover A, so that when the cover is placed on thejar a lug shall fit in each space between adjacent ridges. When thecover is placed on the jar, resting on the shoulder thereof, the lowersides of the lugs 12 b are above the upper sides of the ridges a a, anda turn of the cover either to the right or left engages the ridges underthe lugs. As the cover is turned, bringing the lugs nearer and nearer tothe centers of the ridges, it is held more and more tightly andsecurely, and is held tightest when the lugs approach nearest thecenters of the ridges, the construction being such that the lugs cannever pass the centers.

To render the jar air-tight when the cover is on, an elastic gasket, 0,of suitable material, is placed on the shoulder of the jar before thecover is put in position.

lVhat I claim as my invention is A'sheet-metal fruit-jar cover, A.provided with inwardly-projecting convex ridges a a, in combination witha molded glass fruit-jar, B, provided with outwardl y-proj ectingbeveled lugs b 1), adapted to fit over said ridges, sub stantially asand for the purpose herein specified.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH L. DE STEIGER.
